Hey guys,


Wanted to show you guys the results of my two day dyno excursion....Here is the result of day one's tuning. We just messed with the VAFC....
Today, I decided to go back and try to get the power curve smothed out. The guys suggested changing out my cat for a highflow. We did that and as you see, the power jumped a bit, but smoothed out delivery from 5500 to 6000.

The final sheet shows the results of everyting done (AF/cams/Cat) it compares against my innitial run. I can't believe the improvement. Power is smother and increased across the entire powerband. the car feels great.


what do you guys think?

YV

i pulled 168 wit the same set up on my car... was not impressed with my results..

 

I think my header is the problem...

 

very possible

 

seems a little low, i pulled better numbers with similar setup, but without the cams.

 

does the torque curve look messed around vtec engagement?

 

just out of curiosity, is your ecu chipped or anything, or do you still have the stock redline? from what i saw you have a vafc, so im assuming that you used that to tune it with, and if you still have a stock redline than thats one of your problems. you need to rev higher to squeeze the most power you can out of you ITR cams. you should be making more power than that!!

 

I did have my obd I in for a few runs, but it was running so rich that I couldn't seem to get it to lean out at all. This gave me some pretty poor numbers. immediately after switching to my stock ecu, hp jumped up across the board.

any suggestions?

yeah, my car is completely un-tuned.

 

i dont know dude, im getting a set up similar to yours except im gonna be using hondata, and im shooting for at least 175whp!! the only thing that i could think of would be the redline. thats just my 2 pennies

 

numbers do seem a little bit low.

very good write up though. good step by step write up
